COMMON RAIL Electronic Diesel Injection Analyzer EDIA-5

EDIA-5 diagnostic system is a patent pending, innovative solution for rapid diagnosis of Common Rail injection engines developed by Polish company DeltaTech Electronics. This device is useful in diagnosis of both electromagnetic and piezoelectric injectors. With its help it is possible to analyze also unit injectors control signals. Connected to a computer via USB port allows recording of injector control current change of four injectors at the time and a signal from high pressure rail sensor.

With innovative probes it is possible to visualize injection signal with minimum interference, without removing the injectors or damaging wire insulation.

Recorded waveforms can be used for accurate diagnosis and failure detection of injectors, sensors, high pressure pump and other components of Common Rail system.

Unlike traditional oscilloscopes, difficult to use in a garage, EDIA-5 offers simple and user-friendly operation, without complicated configuration. Acquired waveforms can be stored and compared with each other which gives additional possibilities.

EDIA-5 allows accurate measurement of injection signal times for four injectors and enables to precisely observe rail pressure changes caused by working injectors. This gives very good diagnostic capabilities. An important advantage of the analyzer is small size, simplicity of use and favorable price.

With the EDIA-5 system, we can obtain information on:

  • electrical part of injection system
  • hydraulic part of injection system
  • overall condition of the engine

Diagnosis of electrical part of injection system allows you to:

  • check of injector solenoid condition or a piezoelectric stack through analysis of current control waveform of the injector;
  • check connection (contact) quality through analysis of control waveform;
  • check connection quality between injector plug and the controller;
  • check controller high voltage capacitors charging;
  • validate parameters (voltage, current, time) of control signals generated by the ECU;
  • check starting dose timing during engine start;
  • verify correct operation of the rail pressure sensor.

Diagnosis of hydraulic part of injection system allows you to:

  • check the rate of rail pressure rise which gives information about functionality of high pressure pump;
  • check the pressure of first injector opening at the time of engine starting;
  • check the operation of individual injectors at the time of starting the engine;
  • check the transition from starting dose to normal idling dose;
  • check injection timing and dosage on idling;
  • check injection timing and dosage on increasing speed;
  • check injection timing and dosage on decreasing speed - reduced or no injections;
  • check pre-injection timing and dosage;
  • check main injection timing and dosage;
  • check after-injection timing and dosage;
  • check speed of pressure decay after switching off the engine;
  • check rail control valve operation;

Diagnosis of mechanical part of injection system allows you to:

  • check the difference in injection times resulting from efficiency of individual cylinders - different angular accelerations measured by ECU;
  • indirect check of individual cylinder tightness - cracked cylinder head gasket, piston rings, cylinder, piston, etc.
